(54)	Method of an apparatus for curing an optical disc

(57) It is an object of the invention to provide an apparatus for curing an optical disc (D) capable of efficiently curing ultraviolet curing resin (R) serving as an adhesive relative to disc substrates through which ultraviolet does not transmit. It is another object of the invention to provide a method of and an apparatus for curing an optical disc (D) capable of efficiently curing ultraviolet curing resin (R) serving as an adhesive relative to disc substrates through which ultraviolet hardly transmits. The apparatus for curing an optical disc (D) placed on a rotary holding table (1) and formed by bonding a first disc substrate (D1) and a second disc substrate (D2) by the medium of an ultraviolet curing resin (R) comprises an ultraviolet irradiation peripheral unit (2) disposed around the rotary holding table (1) for irradiating ultraviolet from the peripheral surface of the optical disc (D) toward the inner portion thereof so as to cure the ultraviolet curing resin (R).
